Four teams of students sold iced milo for charity.
They collected $4 for a small cup of iced milo and $6 for a big cup of iced milo.

The table shows the number of cups sold by three of the teams.

	Small cups	Big cups
Team L	17	4
Team M	14	7
Team N	6	12

1. Which of the three teams collected the least money? Give your answer in letter. (Eg A)
2. What was the amount of money collected by Team N?
3. Team M sold as many cups of iced milo as Team P but collected $4 less. How many small cups of iced milo did Team P sell?

(a)
Amount collected by Team L = 68 + 24
= $92

Amount collected by Team M
= 14 x 4 + 7 x 6
= 56 + 42
= $98

Amount collected by Team N
= 6 x 4 + 12 x 6
= 24 + 72
= $96

Team L collected the least money.

(b)
Amount collected by Team N = $96

(c)

	Small cups	Big cups	Total cups	Total amount
Team M	14	7	21	$98
Team P	12	9	21	98 + 4 = $102

Since Team M and Team P sold the same number of cups but Team M collected $4 less, it means that Team P sold more big cups than Team M.

Difference in the total amount collected between Team M and Team P = $4

Difference in the amount collected for every one extra big cup sold by Team P
= 6 - 4
= $2

Number of extra big cups sold by Team P
= 4 ÷ 2
= 2

Number of small cups sold by Team P
= 14 - 2
= 12

Answer(s): (a) L; (b) $96; (c) 12
